RUI: Preparation and Characterization of Dendrimer Templated Au-M Nanoparticles and Catalysts

Bert D. Trinity大学的钱德勒在化学系化学催化项目的支持下，开发了制备固体氧化物负载的纳米颗粒催化剂的新合成技术，并研究了这些多相催化剂的反应机理。 纳米颗粒将在溶液中制备，使用树枝状聚合物包封合成路线，然后沉积在高表面积载体上。 两个动力学为基础的分析技术将被用来探测和评估的催化活性的纳米粒子：选择性抑制将被用来询问的CO氧化活性位点和Hammett关系的好氧苯甲醇氧化将被用来探测纳米粒子表面电荷的变化。 负载型纳米颗粒是一类重要的非均相催化剂，在整个化学工业中使用。 对铂族催化剂中金属功能之间相互作用的基本理解将为设计新的催化剂提供信息，减少对昂贵铂族金属的依赖。 在他们的化学职业生涯早期，将本科生主要是本科院校的本科生融入到这个研究项目中，将激励他们从事这方面的研究，从而提高化学催化的劳动力。

Professor Bert D. Chandler of Trinity University is supported by the Chemical Catalysis Program in the Division of Chemistry to develop new synthetic techniques for the preparation of solid oxide supported bimetallic nanoparticle catalysts and study reaction mechanisms over these heterogeneous catalysts. The bimetallic nanoparticles will be prepared in solution, using a dendrimer encapsulation synthetic route and then deposited onto high surface area support. Two kinetics-based analytical techniques will be employed to probe and evaluate the catalytic activity of the bimetallic nanoparticles: Selective inhibition will be used to interrogate the CO oxidation active sites and Hammett relationships for aerobic benzyl alcohol oxidation will be used to probe changes in nanoparticle surface charge. Supported bimetallic nanoparticles are an important class of heterogeneous catalysts that are employed throughout the chemical industry. A fundamental understanding of the interplay between metal functions in bimetallic catalysts will informs the design of new catalysts with less reliance on expensive platinum group metals. Integrating undergraduate students in a primarily undergraduate institution into this research project early in their chemical career will motivate them to pursue this line of research and consequently enhance the chemical catalysis workforce.
